The Glasgow Jazz Festival has announced its 2015 lineup and in keeping with a festival that in previous years has hosted such diverse artists as Dionne Warwick and David Liebman, it's another trip around the genres, from soul legend Gladys Knight and big band swing from Frank Sinatra Jr through to the free improvisation of the Glasgow Improvisers Orchestra.

The eclecticism isn't confined to the programming: the festival sees the Scottish debut of NeTTwork Trio, featuring three jazz musicians from very different backgrounds. Jeff 'Tain' Watts is the long-standing drummer for Wynton Marsalis; guitarist Stanley Jordan has been keeping a low-ish profile since his technically dazzling late 80s debut; the youngest member, bassist Charnett Moffett, has played with more or less everyone from Sonny Sharrock to Dianne Reeves, and together the trio have been sharing stages in the US with the likes of Pharoah Sanders.

There's Brazilian bossa nova legend Marcos Valle; a solo set from acclaimed English-Bengali pianist Zoe Rahman; and Paul Towndrow and Ray Quigley's With Strings project, paying tribute to Charlie Parker and Clifford Brown's legendary string-accompanied albums. Jazz dynasties are represented by DJ and keyboardist Taylor McFerrin – yes, Bobby is his dad – appearing with rising young drummer Marcus Gilmore, whose grandfather is the great Roy Haynes, although he himself has a regular gig with Vijay Iyer.

As well as this, there's a DJ set from GJF favourite Rebecca Vasmant; Eddi Reader offering a fresh take on Scottish music in Alba: Songs of Scotland with the mighty Scottish National Jazz Orchestra: impressive young Shetland-born, London-based alto player Rachael Cohen and her band; trad jazz from the Nova Scotia Jazz Band, and free improvisation from the GIO with its good friend and a true giant of improvisation, Evan Parker.

There's much more besides, including a lecture from Glasgow University's Graeme Wilson on how improvising is good for body and mind, plus the all-important late night jam sessions at the Rio Club. But we can't resist mentioning one more world-famous act: The Family Stone features original members Jerry Martini (sax), Cynthia Robinson (trumpet) and Gregg Errico (drums), plus Cynthia's own daughter Phunne Stone on various instruments and vocals.

The Glasgow Jazz Festival is at various venues, Glasgow from Wed 24–Sun 28 Jun.
